LOCKED-NUT APPARATUS.

Application filed June 28, 1924.

To all whom t may concern:

Be it known that I, CLARENCE A. Gonsi-IALK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Locked-Nut Apparatus, of which the following is a specification.

This invention relates to locked nuts, that is to say, nuts adapted to be applied to bolts from which they are removed from time to time as occasion may require, but which until the time of removal, it is desirable should be locked and held against any unauthorized manipulation, either by a meddler or a person maliciously inclined. Tt has for its object to improve means or apparatus for locking such a nut, including keyoperated lock mechanism. While the invention may be put to a wide variety of uses it is especially adapted as a spare tire lock for automobiles, and in the accompanying drawings T have illustrated it as used in such connection.

Referring to the drawings- Figure 1 is a sectional view of a spare tire carrier and lock embodying one form of my invention, the locking parts being shown in elevation.

Fig. 2 is a front view of the parts shown in Fig. 1.

Fig. 3 is a view similar to Fig. 1 illustrating another form of my invention; and

Fig. 4 is a front view of parts shown in Fig. 3.

Fig. 5 is a sectional view taken on the line VV of Fig. 1.

In the drawings 2 designates the ring or holder upon which is supported the rim of a spare tire. To this is riveted or otherwise secured a bracket 3 from which extends outwardly a screw-threaded bolt or pin 5 that passes freely through an opening in a clamp piece 4 that is adapted to engage with the tire rim and hold it upon the support 2. The parts thus far described are well known in the art and are standard equipment upon many automobiles. They may be varied in details of construction so far as my present invention is concerned.

A nut 6 engages with the bolt 5 and is employed to bear against the clamp piece 4 and hold it in place against the rim of the tire that may be mounted upon the support 2. A casing 7. is connected with or carried Serial N'o. 723,012.

by the nut, being either integral therewith or a separate piece and secured thereto as may be preferred, in the forms of invention herein illustrated the casing being an extension beyond the nut 6, preferably angular in cross section and larger than the nut.

8 designates a locking post located alongside the bolt 5, and the nut and casing 7 when applied to the bolt. This post is preferably a separable element, being provided at one end with a reduced portion or pin 9 that is adapted to pass through aligning openings 10, 10 formed respectively in the bracket 3 and clamp piece 4. Tn the form of my invention illustrated in Figs. 1 and 2 the post 8 has formed in its outer portion a perforation or opening 11, in which is mounted the body 12 of a lock, which may be of any suitable character, that represented being a pin tumbler lock operated by a key 21. In the face of the lock body there is formed a longitudinal groove or slot 14 into which projects the end of a screw or pin 13 seated in the post 8. This arrangement permits the casing to slide longitudinally in the opening 11.

The casing 7 carried by the nut is located opposite to the portion of the post 8 in which is mounted the lock body 12, and in such casing is formed a socket or recess 15 into which extends the inner end of the lock body when the parts are assembled as represented in Fig. 1. The lock represented is constructed with a rotatable barrel or cylindrical portion 23 eccentrically mounted in the body 12 and adapted to be turned by the key 21. To the inner end of the rotatable barrel 23 is secured a locking plate 16 which is eccentric to the body 12 and is adapted to have its outer end 24 enter a recess 17 provided therefor in the body of the casing 7 when the parts are moved by the key into locking position.

The parts thus far described will be used as follows: After a spare tire has been placed upon the holder the clamp piece 4 is slipped over the bolt 5 and forced into place to hold the tire rim by screwing the nut 6 upon the bolt.

TWhen the nut has been properly tightened it is adjusted so as to bring the casing 7 to the position indicated in Fig. 1, which is made possible by employing a split elastic washer 22 between the inner face of the nut and the clamp piece 4. The post 8 carrying ruaman.
